Asingle strand of dna helix has the code ataggc. which would be the complementary code on the other strand of the helix?
a. auaccg
b. cgctta
c. gcgaat
d. tatccg
the awnser is
d. tatccg

The complementary code on the other strand of the helix will be TATCCG.

Explanation;
During the process of DNA replication, after the annealing of the double helix each of the strand can act as a template for the synthesis of a new complementary strand. During the formation of the complementary strand, each nucleotide base on the template strand binds to another nucleotide base on the complementary strand so as to generate a new double helix. Adenine base (A) pairs with Thyamine base (T), while Guanine base (G) pairs with Cytosine base (C).
